Fluid hammer theory
WebThe increased possibility of a fluid-hammer effect, he says, needs to be heeded by Boeing and airline mechanics. Regardless of whether he's right about the Aloha accident, … WebWater Hammer is a pressure surge or wave that occurs when there is a sudden momentum change of a fluid (the motion of a fluid is abruptly forced to stop or change direction) within an enclosed space (Water Hammer). This commonly occurs in pipelines when a valve is closed suddenly at the end of a pipeline where the velocity of the fluid is high.
